Process of making a seal and apparatus for sealing doublewide manufactured homes

Abstract

A process for making a sealing material for sealing doublewide manufactured homes includes the steps of selecting an elongated seal core made of a foamed polymer and selecting a flexible polymer covering sleeve for loosely covering the selected seal core and covering the seal core with a loose fitting covering sleeve. The covering sleeve is then shaped to form a skin over the seal core by forming a pair of flanges from the slack material in the covering sleeve with a folded portion of the covering sleeve and attaching the folded portions together to form flanges. A seal for a doublewide manufactured home is formed by the process and has an elongated polymer foam core covered by an elongated flexible polymer sleeve and having a pair of elongated flanges formed with folded slack material in the flexible polymer sleeve which folded flange portions are attached together, such as by sewing. A predetermined density foam core material of a larger size is covered with a woven polypropylene material.

I claim: 
     
       1. A process for making a sealing material for sealing doublewide manufactured homes comprising the steps of: selecting an elongated seal core made of a foamed polymer having a generally square cross section;   selecting a flexible polymer covering sleeve of flexible woven polypropylene sized for loosely covering said selected seal core;   covering said selected seal core with said loose fitting covering sleeve to thereby leave slack material between said seal core and said polymer covering sleeve;   shaping said loose fitting covering sleeve to said seal core by forming a pair of flanges with the slack in said covering sleeve with a folded portion of said covering sleeve; and   attaching said folded portions of each said flange together; whereby a doublewide sealing material is formed with two flanges for sealing between doublewide sections of a doublewide manufactured home.   
     
     
       2. A process for making a sealing material for sealing doublewide manufactured homes in accordance with claim 1 in which the step of selecting an elongated seal core includes selecting an elongated polymer foam material at least 2.5 centimeters thick. 
     
     
       3. A process for making a sealing material for sealing doublewide manufactured homes in accordance with claim 2 in which the step of selecting an elongated seal core includes selecting an elongated seal core of polyurethane of approximately 1.2 density.
